    Many of the o-rings in faucets and valves need to slide or rotate. In a sharkbite, once it is installed, it's stationary, so it should be pretty long-term. Neoprene as used in a no-hub seems to last a very long time, and the o-ring is probably similar. deriding them out of hand is your right, but may be unfounded. Testing says they last. Improper installation can damage them and could either cause them to fail on install, or early.

    Valid points on the comparison between mobile & static rubber parts.
    My point...observe the condition of a toilet flapper used on public water supplies after just a few years in some areas.

    Jim, mechanical gaskets aren't under pressure...and my state only allows them underground.

    My point would be the o-ring in a Sloan Valve...
    They seem to last a few years...

    ...and they're intentionally made to be accessed for replacement.

    Still though the only time they ever get replaced is when you cut one sliding the valve back into the stop check...
    They don't mysteriously go bad!
